Let’s look at how you can identify and fix these problems.
12 Ways to Fix Phone Battery Draining Fast
1. Check Which Apps Are Consuming Your Battery
check your phone’s battery usage. Some applications consume battery power even when you are not actively using them.
For example, social media apps, navigation apps, video streaming platforms, and games may use significant battery power.
On Android:
- Open Settings.
- Go to Battery or Battery Usage.
- Check the battery consumption of individual apps.
- Identify applications using unusually high battery power.
- Restrict background activity for apps that you rarely use.
On iPhone:
- Open Settings.
- Tap Battery.
- Check the battery usage section.
- Review which applications consume the most power.
- Tap an app to understand its battery activity.
If an application is consuming an unusually high amount of battery, update it, restrict its background activity, or uninstall it if you no longer need it.
2. Reduce Screen Brightness
Your smartphone display is one of the major contributors to battery consumption. Using maximum screen brightness for long periods can drain your battery faster, particularly when watching videos, playing games, or browsing social media.
How to fix it:
- Reduce screen brightness to a comfortable level.
- Enable Adaptive Brightness on Android.
- Enable Auto-Brightness on iPhone.
- Reduce screen timeout to 15 or 30 seconds.
- Avoid keeping the screen active unnecessarily.
These small adjustments can help improve everyday battery life.
3. Turn Off Unnecessary Background Apps / Force stop Apps
Many applications continue performing activities even after you close them.
For example, applications may refresh content, synchronize data, check for notifications, or access location services in the background. You do not need to disable every background application. Instead, identify apps that consume excessive power and restrict unnecessary activity.
On Android:
- Open Settings.
- Go to Apps.
- Select the application.
- Find Battery or App Battery Usage.
- Restrict background usage if appropriate.
On iPhone:
- Open Settings.
- Select General.
- Tap Background App Refresh.
- Disable it for applications that do not need frequent background updates.
Remember that restricting background activity may delay notifications or updates from certain applications.
4. Turn Off Location Services When Not Required
GPS and location services help applications identify your current location. Such as Google Maps, Uber, food delivery platforms, and weather applications may access location information. If several applications continuously access your location, they can contribute to battery consumption.
You do not have to turn off GPS completely. Managing unnecessary location permissions is usually a better approach.
How to fix it:
- Open your phone’s Location settings.
- Review which applications have location permission.
- Allow location access only when necessary.
- Choose While Using the App instead of Always, where available.
5. Disable Always-On Display
If your phone battery is draining quickly, try disabling Always-On Display. Some smartphones have an Always-On Display (AOD) feature that displays the time, date, notifications, and other information even when the screen is locked. Although this feature is designed to use relatively little power, it can still contribute to battery consumption.
On Android:
- Open Settings.
- Search for Always-On Display.
- Open the feature settings.
- Turn it off or configure a schedule.
On iPhone:
- Open Settings.
- Tap Display & Brightness.
- Select Always On Display, if supported.
- Turn it off if you do not need it.
The exact settings may vary depending on your smartphone model.
6. Use Wi-Fi Instead of Mobile Data When Possible
When mobile signals are weak or unstable, your device may use more power searching for a reliable connection. Your phone constantly communicates with nearby mobile towers to maintain a network connection. This can happen inside buildings, basements, elevators, and areas with poor network coverage.
Poor network coverage is an often-overlooked reason for smartphone battery drain.
How to improve battery life:
- Connect to a reliable Wi-Fi network when available.
- Avoid unnecessary switching between mobile networks.
- Use Airplane Mode when you are in an area with no network coverage and do not need calls or mobile connectivity.
- Consider switching from 5G to 4G if 5G coverage is weak and your phone supports this option.
7. Reduce Screen Refresh Rate
The available options depend on your smartphone. Modern smartphones offer high refresh rates such as 90Hz, 120Hz, and even 144Hz. A higher refresh rate makes scrolling, animations, and gaming look smoother. However, it may consume more battery power than a lower refresh rate. If your phone supports refresh-rate adjustment, try switching to Standard or Auto mode.
General steps:
- Open Settings.
- Go to Display & Brightness or Display.
- Find Screen Refresh Rate.
- Select Standard, Auto, or a lower refresh rate.
This can be particularly useful if you frequently use your phone for browsing and social media.
8. Check for Software and App Updates
Outdated applications or software bugs can sometimes cause unexpected battery consumption. Manufacturers regularly release updates to improve performance, fix bugs, and optimise battery usage.
What you should do:
- Check for available Android or iOS updates.
- Update applications through Google Play Store or Apple App Store.
- Restart your phone after important updates.
- Check whether the battery problem continues after a few days.
Note that battery consumption may temporarily increase after a major software update because the phone performs background optimisation.
9. Enable Battery Saver or Low Power Mode
Almost every modern smartphone includes a power-saving feature. This feature reduces unnecessary background activity and adjusts certain system functions to extend battery life. Depending on your phone, power-saving mode may restrict background syncing, visual effects, performance, and some other features.
It is particularly useful when your battery level is low and you cannot charge your phone immediately.
On Android:
- Open Settings.
- Go to Battery.
- Select Battery Saver or Power Saving Mode.
- Turn it on.
On iPhone:
- Open Settings.
- Tap Battery.
- Enable Low Power Mode.
10. Avoid Excessive Phone Heating
High temperatures can also cause the battery to drain faster. Your phone may become hot when playing demanding games, recording videos, using navigation, charging, or running multiple intensive applications. Heat is one of the factors that can negatively affect smartphone battery performance and lifespan.
Note : If your phone repeatedly overheats during normal use, consider getting it checked by an authorised service centre.
Tips to prevent overheating:
- Avoid playing heavy games while charging.
- Do not leave your phone in direct sunlight.
- Close demanding applications when they are not needed.
- Avoid using your phone heavily in very hot environments.
- Use a compatible charger recommended by your manufacturer.
11. Check Your Phone’s Battery Health
Smartphone batteries gradually lose their capacity as they age. This means an older phone may not hold as much charge as it did when it was new.
For example, a phone that originally lasted an entire day may eventually require charging more frequently.
How to check battery health on iPhone:
- Open Settings.
- Tap Battery.
- Open Battery Health or Battery Health & Charging, depending on your iPhone model.
- Review the available battery health information.
How to check battery health on Android:
